[0034] The hydraulic oil tank is a component in the hydraulic system of a telescopic forklift truck, and is used to store hydraulic oil. In the traditional solution, the hydraulic oil tank is usually arranged on both sides of the frame longitudinal beam and connected to the frame longitudinal beam, which has the problems of large space occupation and low frame structural strength. In this regard, the prior art provides a frame structure, which includes a left side plate and a right side plate, and the hydraulic oil tank is arranged between the left side plate and the right side plate, and the two sides of the hydraulic oil tank are respectively connected to the left side plate and the right side plate, so that by changing the position of the hydraulic oil tank, the space occupied by the hydraulic oil tank is saved, and at the same time, the structural strength of the frame can be improved by the box body of the hydraulic oil tank. However, there is still a problem that this solution has limited improvement on the structural strength of the frame.

[0035] In view of the above problems, this embodiment provides a frame assembly to solve the problem that the prior art has limited improvement in the structural strength of the frame, and can be used in the field of vehicle technology, and specifically can be applied to telescopic arm forklifts.

[0036] Reference Figure 1-Figure 5 The frame assembly includes a frame body 1 and a hydraulic oil tank 2. The frame body 1 includes two parallel and spaced longitudinal beams 11. In some embodiments, the frame body 1 also includes a plurality of cross beams arranged between the two longitudinal beams 11. The plurality of cross beams are spaced apart, and both ends of the plurality of cross beams are respectively connected to the two longitudinal beams 11. The hydraulic oil tank 2 includes a bottom plate 21 and a top plate 22. The bottom plate 21 is a straight plate, and the top plate 22 is formed by bending the straight plate. Both ends of the top plate 22 are connected to the bottom plate 21. The space enclosed by the bottom plate 21 and the top plate 22 has a receiving chamber 200 for receiving hydraulic oil. The two sides of the bottom plate 21 are respectively connected to two longitudinal beams 11, and the two sides of the top plate 22 are respectively connected to two longitudinal beams 11, so that the hydraulic oil tank 2 is arranged between the two longitudinal beams 11, which can save space in the vehicle chassis. At the same time, the two sides of the bottom plate 21 and the two sides of the top plate 22 are respectively connected to the two longitudinal beams 11, which can improve the structural strength of the frame assembly. In addition, since the top plate 22 is formed by bending the straight plate, compared with the straight plate, the structural strength of the frame assembly can be further improved. In the frame assembly, the space occupied by the hydraulic oil tank 2 is small, and the structural strength of the frame assembly is high.

[0037] Continue to refer to Figure 1-Figure 5 , the above-mentioned bottom plate 21 and top plate 22 generally need to be pickled and phosphated before assembly, so as to control the cleanliness of the hydraulic oil tank 2. The side walls of the accommodating cavity 200 close to the longitudinal beam 11 also need to be pickled and phosphated. If the longitudinal beam 11 is directly used as the cavity wall of the accommodating cavity 200, the entire longitudinal beam 11 needs to be pickled and phosphated, which will increase production costs. To address this problem, the hydraulic oil tank 2 also includes two side plates 23, both of which are parallel to the longitudinal beam 11 and are spaced apart. The bottom plate 21, the top plate 22 and the two side plates 23 surround the accommodating cavity 200, and the two side plates 23 also need to be pickled and phosphated before assembly.

The first bending plate 221 is parallel to the vertical plane, the second bending plate 222 is parallel to the horizontal plane, and the angle between the third bending plate 223 and the second bending plate 222 is an obtuse angle. Since other structures are generally arranged between the two longitudinal beams 11 of the frame body 1, such as a fuel tank and connecting pipes, etc. The first bending plate 221 can be arranged on the side where no other structures are required to be installed, so as to maximize the volume of the accommodating cavity 200. The third bending plate 223 is arranged as a whole at an angle, and along the direction gradually approaching the bottom plate 21, the third bending plate 223 gradually moves away from the first bending plate 221, so there is a certain space above it obliquely. The third bending plate 223 is arranged on the side where other structures need to be installed, leaving more installation space for other structures.
